Screw-Type Evaporator

Screw Evaporator

Product Overview

Screw blade film evaporators are evaporative and distillation equipment that use high-speed rotation to distribute liquids into a uniform film for evaporation or distillation. They can also be used for deodorization, de-foaming reactions, as well as heating and cooling operations. They are suitable for industries such as food, light industry, petroleum, and chemical engineering.

Performance and Features

This equipment features a centrifugal sliding groove rotor, which can form a thin film even at very low flow rates. The adhered sediment in the inner surface of the cylinder's evaporating section can be rapidly removed by the movable scraper. Compared to fixed gap scrapers, the evaporation capacity can be increased by 40-69%. It boasts the following performance and features:

1. High thermal conductivity, large evaporation capacity, with evaporation intensity up to 200KG/M2·HR, and high thermal efficiency.

2. Short material heating time, approximately 5 to 10 seconds, and operates under vacuum, beneficial for heat-sensitive materials. Ensures no decomposition of various components, guaranteeing product quality.

3. Wide range of viscosity adaptability; can handle both high and low viscosity materials. Material viscosity can reach up to 100,000 centipoise (CP).

4. Changing the scraper groove rotation direction can adjust the material's residence time in the evaporator.

5. The inner wall of the evaporator cylinder is precision bored and polished, making the surface less prone to scaling and fouling.

6. User-friendly operation, easy to adjust product specifications; can maintain continuous production under enclosed conditions.

7. The equipment occupies a small footprint, features a simple structure, is easy to maintain, and clean.
